The alignment of respiration to sensory-motor events is shaped by expected effort.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Humans often align their respiration with external events, which may optimize neural resources for perception and action. This may adjust neurophysiological processes related to neural excitation, attention, or arousal to optimize task performance. However, it remains unclear whether this alignment is a passive entrainment to a task's overall rhythm or an active process selectively aligning respiration more to highly demanding events. We tested this by recording respiration during three visual discrimination experiments that manipulated the importance of individual trials by imposing response deadlines or manipulating trial value and difficulty. We found that participants align their respiration more consistently for trials with short deadlines or trials presenting high-value and high-difficulty. This demonstrates that respiratory alignment is dynamically modulated on a trial-by-trial basis according to anticipated effort or task demands. Hence, respiration serves as an active tool to strategically allocate cognitive resources for sensory-motor challenges.
